How many oz did your 4 month old ate ?

My daughter is 4 months old she’ll be turning 5 months in two weeks. Right before she turned 4 months she was eating 4-5oz every 2-3 hours but then I started to notice she would cry every time she would finish her bottle I would burp her and she would still cry. So then that’s when I decided to bump her one more ounce so then she would drink 5-6oz at first she did ok but then last week she started again to cry after each feeding and I took her to her wellness appointment she had lost a little weight just like 3 oz doctor said it’s not that big of deal but she shouldn’t lose weight I told her the ounces she was drinking and she said that’s the right amount that I’m giving her but then when my mom saw my daughter she was like omg she’s so skinny you need to feed her more!! Because my mom said that it made me think am I really not feeding her enough is that why she cries when she finishes the bottle my mom gave her 8oz and she finished the whole bottle! She didn’t even cry after so then I’m like ok 7-8 oz now and she’s like a whole different baby! Everyone that lives with me says she’s so much happier now she even gained the weight she lost but today I took her to a gastroenterologist just to make sure nothings going on inside her that making her lose weight and she was pooping a lot (4-5 diapers almost a week) the doctor said she’s fine but I’m giving her way to much she still eats around 2.5-3 hrs sometimes if she takes naps she’ll go 3-4hrs with out eating but she seems much better with 7-8oz idk what to do doctor told me she should be eating 5 bottles but I’ve counted she drinks 6-7bottles a day. The only thing I want for my baby is for her to be nice and full and for her not to keep losing weight 🥺 I know each baby is different but why do I feel bad because the doctor basically told me that ugh 😩 how many oz did your little one eat at 4-5months ?
